The Koopalings (known as Bowser's Minions in the PAL version and クッパ7人衆, The Seven Koopa Bunch in the Japanese version of Super Smash Bros. 4, sometimes referred to as Koopa Kids) are a clan of seven siblings that follow Bowser and are recurring villains in the Mario series. Their individual names are Larry Koopa, Morton Koopa Jr., Wendy O. Koopa, Iggy Koopa, Roy Koopa, Lemmy Koopa, and Ludwig von Koopa, in the order they were fought in their debut game, Super Mario Bros. 3. While initially unnamed in their original Japanese appearance, Dayvv Brooks of Nintendo of America gave each of them names after famous musicians, with the exception of Larry Koopa.

The Koopalings were originally described as Bowser's children and depicted as such in other media. However, this backstory was eventually discarded and they have only been referred to as particularly high-ranking minions of Bowser's following their reintroduction after Bowser Jr.'s debut. Shigeru Miyamoto also later stated in a 2012 interview that Bowser Jr. is an only child, further distancing the relationship between Bowser and the Koopalings; despite this, re-releases of games featuring the Koopalings have not made an attempt to change this backstory. Super Smash Bros. 4 later made light of this confusing relationship, with Pit's Smash Taunt for the characters noting that their Junior Clown Cars are mass-produced as opposed to Bowser Jr.'s personalized vehicle; Viridi also notes that the relationship between the Koopalings and Bowser is "a real mystery". Recent official materials by Nintendo implies that the Koopalings' relationship with Bowser is intentionally kept ambiguous, although they are confirmed to be related to each other.

Larry (ラリー, Larry) is the youngest of the Koopalings. He is the first one fought in Super Mario Bros. 3, and that fact has led to speculation that the Koopalings following him are ordered by age. However, the order varies in several later games, starting with Super Mario World, where Iggy is fought first and Larry is fought last (Larry reprises his role as first later in New Super Mario Bros. Wii). Larry is associated with grassy plains in most of the games he appears in. Larry's rear-facing mohawk-like hair and shell are colored electric blue, and he has large blue eyes. He is the second smallest Koopaling, after Lemmy. He is currently voiced by Lani Minella. Unlike the other Koopalings, Larry's namesake is ambiguous, and he is possibly the only Koopaling not named after a famous personality. He has been previously reported to be named after either Larry King, an American radio and television personality, or Larry Mullen, Jr., drummer for the Irish rock band U2. Dayvv Brooks, however, stated in a 2015 interview that "he just looked like a Larry." The title given to Larry in the Boxing Ring is "The Youngest" in Smash Wii U and Ultimate.

Roy (ロイ, Roy) has a design typical of a "bad boy", having shades and being heavily associated with heavy weaponry (such as his Bill Blaster from New Super Mario Bros. U). He is the fifth Koopaling fought in Super Mario Bros. 3, serving as the boss of the sky world. Roy's environmental associations are among the most inconsistent of the Koopalings, having been grassy plains, the desert, and a cave. He has a purple shell, a pink head, and wears hot pink shades. He bears two fangs, like Larry. He is voiced by Dan Falcone, and is named after American rockabilly singer Roy Orbison, who also served as the inspiration for his shades. The title given to Roy in the Boxing Ring is "The Cool One" in Smash Wii U and Ultimate.

Wendy (ウェンディ, Wendy) is the only female Koopaling. She's heavily associated with tropical locations and water, even having an attack that shoots life saver rings in Super Mario Bros. 3, where she is the third boss. She is the third smallest Koopaling, after Larry and Lemmy. Wendy wears a pink bow with polka-dots, pink heels, golden bracelets on her wrists (instead of spiked wristbands like her cohorts), pink lip-stick, and a bead necklace; she's the only Koopaling with accessories that aren't shades or glasses. She has full lips (unlike her associates), blue eyes, and a pink shell. Voiced by Lani Minella in most games and by Ashley Flannegan in Mario Kart 8, Mario & Luigi: Paper Jam, Mario Kart 8 Deluxe, and Mario & Luigi: Superstar Saga + Bowser's Minions, she is named after Wendy O. Williams, lead singer of the American punk band Plasmatics. The title given to Wendy in the Boxing Ring is "The Bold Beauty" in Smash Wii U and Ultimate.

Iggy (イギー, Iggy) is the first Koopaling to be fought in an equal number of instances to Larry: in Super Mario World and Mario & Luigi: Superstar Saga. Before New Super Mario Bros. Wii, Iggy's hair was the same as Lemmy's, being a rainbow-colored mohawk, and his eyes had multiple rings within them that made him look hypnotized. From New Super Mario Bros. Wii on, Iggy's hair has been neon green and is shaped similarly to a palm tree. According to the cartoon shows produced by DIC Entertainment, Iggy is Lemmy's twin brother. Iggy is commonly associated with jungle and forest areas (matching his color scheme), and is implied in New Super Mario Bros. Wii and New Super Mario Bros. 2 to be a mechanical genius with great agility, as well as being known for his deranged and crazy personality. Iggy wears glasses and his irises are surrounded by blue loops (remnant of his older design's eyes; his eyes are also the largest of the Koopalings'), and his shell is green with purple accents. Iggy has a longer shell than his cohorts, and is taller than all of them. Voiced by Mike Vaughn, he is named after Iggy Pop, lead singer of the American rock band The Stooges; as of 2019, he is the only Koopaling whose namesake musician is not deceased. The title given to Iggy in the Boxing Ring is "The Laughing Prankster" in Smash Wii U and Ultimate.

Morton (モートン, Morton) has the most consistent encountering order among the Koopalings, as he is the second castle boss fought in Super Mario Bros. 3, Super Mario World, Mario & Luigi: Superstar Saga, and New Super Mario Bros. U. He mostly presides in desert or mountain worlds, with the latter's landscape matching his color scheme. Morton is the largest Koopaling, and some of his attacks involve hammers and stomps that cause quakes to show for it. He has very small eyes, a snout like Bowser's, very little hair, a black shell, and is the only Koopaling with skin that is not yellow-orange (his is a dark gray). Voiced by Lani Minella, he is named after Morton Downey, Jr., an American television host whose eponymous program, The Morton Downey Jr. Show, became one of the first well-known "Trash TV" programs. The title given to Morton in the Boxing Ring is "The Enforcer" in Smash Wii U and Ultimate.

Lemmy (レミー, Lemmy) is the smallest Koopaling, and is Iggy's twin brother according to the cartoon shows produced by DIC Entertainment. Lemmy shared Iggy's hairstyle until New Super Mario Bros. Wii, wherein Iggy got a new one. Lemmy, also like Iggy, is often shown to be klutzy and dizzy most of the time, and is normally seen balancing atop or holding an orange ball with stars on it. Lemmy is mostly associated with ice and presides as the boss of ice worlds in twogames. He has a rainbow mohawk, orange "bands" on the back of his head, dizzy eyes, an orange shell, and bears no teeth (like Wendy). Lemmy shares many traits with real-world clowns. Voiced by Lani Minella, he is named after the late Ian Fraser "Lemmy" Kilmister, lead vocalist and bassist for English heavy metal band Motörhead. The title given to Lemmy in the Boxing Ring is "Wacky War Machine" in Smash Wii U and Ultimate.

Ludwig (ルドウィッグ, Ludwig) is claimed to be the oldest Koopaling in the Super Mario Bros. 3 strategy guide; the same guide also states that he is Bowser's second in command, though this plot point has been rendered invalid with the debut of Kamek and Bowser Jr., his caretaker and son, respectively. However, this does not stop him from being the de facto leader of the Koopalings. He is the last Koopaling fought in his debut and consistently as of New Super Mario Bros. Wii. However, in Super Mario World Ludwig is the fourth Koopaling to be fought, though he is the only one with a unique fighting style. Ludwig is heavily associated with the sky and clouds, presiding as the boss of those kinds of levels in most of the games he's appeared. He is also shown to have enhanced jumping capabilities in New Super Mario Bros. Wii, similar to Yoshi. Ludwig has the most voluminous hair of the Koopalings, and expresses high levels of cunning and skill. He has small eyes (like Morton), blue hair, a blue shell, and bears a single fang from his mouth. Voiced by Mike Vaughn in most games and David J. Goldfarb in Mario Kart 8 and Mario Kart 8 Deluxe, he is named after German composer and pianist Ludwig van Beethoven, even sharing his namesake's hairstyle. The title given to Ludwig in the Boxing Ring is "Pompous Prodigy" in Smash Wii U and Ultimate.

While the Koopalings do not physically appear in-game, they are indirectly mentioned in Bowser's trophy description; as this trophy was written prior to the introduction of Bowser Jr., it directly refers to the group as his own seven children.

Additionally, while Morton himself does not appear in Brawl, a reference to him is made in the form of Bowser's white palette swap, which is based on the former's original, pre-New Super Mario Bros. Wii design.

All seven of the Koopalings appear as playable characters in Super Smash Bros. 4 as alternate costumes for Bowser Jr., who is in his Junior Clown Car. All are named by the announcer and have their own voices and sound clips. Their mass-produced Junior Clown Cars have yellow bulbs for eyes, and their cockpit rims and propellers are colored differently for each Koopaling (Morton's are gray, for example). Their voice clips are reused from the New Super Mario Bros. series. All of the Koopalings also have their own associated trophy, though these trophies are obtained from the Trophy Shop instead of being rewarded after completing Classic Mode.

While some of the Koopalings have different proportions than Bowser Jr. in regards to weight or height, all of them are sized more similar to him in-game, causing some of the Koopalings to look slightly different from their depictions in the official games. However, Bowser Jr.'s reveal trailer appeared to show the various Koopalings more accurately in regards to their actual proportions, though this was later reverted slightly for the final builds of SSB4. To some extent, the Koopalings' sizes in the game could be compared to their earlier in-game appearances in their first few appearances, like in Super Mario Bros. 3 or Super Mario World, where they were nearly all the same size.

In the Nintendo 3DS version, character trophies are outlined in the Trophy Gallery just as fighters are in standard gameplay, provided the option is enabled. The trophies for the Koopalings acknowledge their fighter status by giving them properly rendered trophies with outlines, despite the trophies being random drops either in-game or from the Trophy Shop.

The leader of the Koopalings, with aggressive tendencies to match. He's easily recognized by his tall, blue hair. In New Super Mario Bros. Wii, he makes his appearance in World 1. You might think he's tough, with his blue fireballs and shell spins, but his patterns are actually pretty easy to read.

The youngest of the Koopalings, with a serious case of little-brother syndrome to match. He's easily recognized by his tall, blue hair. In New Super Mario Bros.

Roy

This heavy guy is one of the Koopalings and likes throwing his weight around. His pink sunglasses might not make him seem evil, but the speed he can go from slacker to soldier certainly does. In Super Mario Bros. 3, he causes earthquakes to stop Mario in his tracks, all while attacking with blasts of magic. Nasty stuff!

Wendy

Of all the Koopalings, Wendy's the only girl. She's bold, bossy, big headed, and sees Peach and Daisy as her rivals. Despite her tomboyish nature, she's not afraid to show off her feminine side with a pink bow and heels. In New Super Mario Bros. U, she shows off her graceful ice-skating skills with a spin or two.

Iggy

One of the Koopalings. Iggy wears black-rimmed glasses, has hair that's sort of pineapplish, and is known for being a bit of a prankster. He talks in a cutesy way but laughs like a maniac. Also, he seems to like taming Chain Chomps, and in New Super Mario Bros. 2, he gets a rampaging Chain Chomp to help him take on Mario.

Morton

The biggest of the Koopalings. Morton stands out due to the three strands of hair on his head and...oh, the big star on his face. He's more brawn than brains, and in New Super Mario Bros. 2, he appears in World 4, where he'll stay glued to the spot until you attack him. Maybe he just can't be bothered to move!

Lemmy

The smallest and nimblest of the Koopalings, Lemmy is a little rascal with a wacky, childlike look on his face. In New Super Mario Bros. U, he's the boss of World 1 and rides a giant ball while his colorful mohawk sways in the breeze. Don't underestimate him, though—his ball attacks are trickier than they look!

Ludwig

The cleverest of the Koopalings, easily recognized by his big tufts of hair. He's got a mature air about him, but he likes to show off and can sound a bit pompous. In New Super Mario Bros. Wii, he's the boss of World 7 and torments Mario by firing homing magic blasts and floating too high in the air to be jumped on.

In the 3DS version, Larry's trophy says he is the "leader of the Koopalings, with aggressive tendencies to match." This is corrected in the NTSC Wii U version, but the PAL release retains this and labels him Leader of the Seven Minions.

In Super Smash Bros. Ultimate, the Koopalings return as playable characters accessible via Bowser Jr.'s alternate costumes. They are once again 'unlockable characters', like in Super Smash Bros. for Nintendo 3DS. Just like in the previous game, their attacks and statistics are identical to Bowser Jr.'s and (with the exception of the announcer, crowd, and character selection, all of which say and/or display their own names) the game does not acknowledge them as separate characters from Bowser Jr. in battle records and other miscellaneous aspects, such as Classic Mode. Unlike in Super Smash Bros. 4, the Koopalings now use their magic wands (from the New Super Mario Bros. games) for any occasion where Bowser Jr. would use his hammer. These occasions include all corresponding attacks, their side taunt, and one of their victory poses. Akin to their trophies in Super Smash Bros. 4, all of the Koopalings also have their own associated Fighter Spirits, although they can only be obtained from the Shop instead of being rewarded after completing Classic Mode.

Due to the seven Koopalings being acknowledged as separate characters from Bowser Jr., Wendy O. Koopa can technically be considered the first female villain to be playable in the Smash Bros. series.

Iggy Koopa and Roy Koopa are the first playable characters in the Super Smash Bros. series to wear glasses.

Lemmy's trophy in the Nintendo 3DS version.

Despite being yellow in-game, the rim and propeller of Lemmy's Junior Clown Car is orange in his trophy in the 3DS version.

Larry is the only Koopaling that can potentially appear in Super Smash Bros. for Wii U's Classic Mode. If the player has defeated Bowser Jr. in the first three rounds of a playthrough, it is possible to encounter another Bowser Jr. in rounds 4 or 5, as an opponent in a team battle; in this case, Larry will fight in Bowser Jr.'s place, but as Bowser Jr. has no chance of appearing again, Larry can be the only Koopaling to appear in the mode. In such a fight, the text by the game's portraits in-battle will incorrectly refer to Larry as Bowser Jr.

In Ultimate, Mario, Yoshi, and Peach are the only characters who face all of the Koopalings in each of their Classic Mode routes.

Mario fights the Koopalings in the same order he faced them as bosses in Super Mario Bros. 3, Yoshi fights them in the same order as in Super Mario World (his debut game), and Peach fights them in the same order as in New Super Mario Bros. U.

Larry, Iggy, and Lemmy are the only Koopalings who aren't fought outside of the team.

Out of the other four Koopalings fought by other characters, Morton is the only Koopaling to be fought in more than one Classic Mode route; being in both Ike and Incineroar's Classic Mode routes each.

In Smash 4, all of the Koopalings and Bowser Jr. have the exact same animations except for Lemmy. When he is dizzy, his pupils move around in circles rather than the dizzy animation for the rest of Koopalings.
